West Ranch -A- #521 (API 42-239-32372) is a plugged well in Jackson County, plugged July 24, 1991, last operated by Hilcorp Energy Company.

The RRC has issued 2 drilling permits between 1987 and 1990, permitted to 9,000 ft.

It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Completion filings report 5 formation tops, including Miocene (undifferentiated), Greta, Ward, 41-A.

Its lease has reported 267K barrels of oil and 5M mcf of gas since January 1993, with no volume in the three years through April 2026. The lease carries 27 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
